MACHINE FOR JOINTING AND SHAPING SHINGLES.

SPECIFICATION forming part of Letters Patent No. 368,117, dated August9, 1887.

Application filed October 15, 1886. Serial No. 216,334. (No model.)

To all whom, it mag concern:

Be it known that I, ALFRED T. S'rnnsoN, of Eureka, in the county ofHumboldt and State of California, have invented anew and ImprovedMachine for J ointing and Shaping Shingles, of which the followingisafull, clear, and exact description. 1

My invention relates to shingle-machines, and has for its object to takethe shingles as they'leave the shingle-saw, bunch them radially in themachine, ornament the ends thereof in any desired fashion, andsimultaneously joint their upper longitudinal edge.

The invention consists in the construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the machine, and Fig.2 is a front elevationthereof. Fig. 3 is an elevation from, the inner side of the machine, asindicated by the line 00 00 in Fig. 1. Fig. 4 is a plan View of ashingle as it leaves the shingle-saw, the dotted lines showing theamount of jointing to be done; and Fig. 5

illustrates the form of the shingle after leaving my machine when knivesof the form shown are employed.

In the construction of my shingle-machineI employ two horizontalparallel frames, .1 and 2, supported upon suitable legs, 3, a properdistance apart.

Upon the upper frame, 1, near the forward end thereof, a rotary table,3, is pivoted, consisting of concentric circular plates 4 and 5, madeintegral with vertical horizontally-projecting arms 6, which armsradiate equidistance apart from the center of said table to a pointbeyond the outer circular plate, 4, forming thereby six or moreV-shapedcompartments, 7, of equal size, adapted to receive the shingles8, as will be hereinafter set forth.

The pivotal pin 9 of the rotary table 3 is journaled atthe top in oneend of ahorizontal bar, 10, which, extending above said table, isusually curved outwardly and downwardly to an attachmentat its lowervertical end with one of the supporting-legs 3. The said curved bar 10is provided with an integral apertured vertical offset, 11, near itsengagement with the pivotal pin 9 of the table, adapted to form abearing for the forward end of a rectangular horizontal cutter-head, 13,earryinglongitudinally of the same cutter-bars 11. The said cutter -headis made to extend rearward, slightly elevated above the radial arms 6 ofthe table 3, to find a hearing at its rear end in a projection, 15,formed upon the forward vertical arm of a U-bar, 16, which bar, havingthe said arm secured to a rear transverse brace, 17, of the upper frame,1, is arched in a right line to the rear, its other vertical arm beingsecured at the back of said frame. The shaft of the horizontalcutter-head 13 is provided with a pulley, 12, upon the rear end thereof.Between the upper and lower frames, 1 and 2, at the forward end of themachine, a vertical shaft, 18, is journaled, carrying a pulley,

I that point a pinion, 22, and between the frames a toothed wheel, 23,connection between the two shafts being had through a train of gearing,24. The said train of gearing may consist of any ordinary combination toreduce speed, as the object thereof is simply to effect a reduction fromthe rapid motion of the pulley 19 and transmit slow motion to the pinion22 of shaft 21, which said pinion 22 is adapted to mesh with a gearedfeed-wheel, 25, secured to the under side of the inner circular plate,5, of the table 3. In this manner a steadycontiuuous slow rotarymovement is imparted to the said table.

A semicircular guide-plate, 26, is attached centrally to the front ofthe upper frame, 1, from whence it extends, partially encircling therotary table 3, at an elevation above the same about one-half the heightof the radial arms 6 thereon, to a position to the rear of the forwardarm of the U-bar 16. The purpose of this guide-bar is to keep theshingles in proper alignment when placed in the compartments 7, as shownin Fig. 1.

Within the vertical arms of the U-bar 16 IOO horizontal shafts 27 and 28are journalcd, the shaft 27 upon a plane with the top of the upperframe, 1, and the shaft 28 above the same.

The lower horizontal shaft, 27 is provided with a pulley, 29, keyedthereon outside the rear vertical arm of the said U-bar, while upon theother end, outside the forward vertical arm of the bar 16, acutter-head, 30, is detaehably secured thereto, which cutter-head may beof any desired shape, that shown in the drawings being more or lesstriangular, and a similar cutter-head, 31, is adapted to be likewisesecured to the forward projecting end of the upper longitudinal shaft,28, the two cutterhcads being positioned parallel, as the oneis purposedto act in conjunction with the other. Each of the said cutter-heads isso positioned as that when the knives are secured thereto the ends ofthe shingles clamped in the compartments of the rotary table will beroughed thereby into any shape required, according to the form of knifeused. The aforesaid upper shaft, 28, is provided with a pulley, 32,keyed thereon within the U-bar 16.

A vertical shaft, 33, is journaled in proper bearings, 34, secured tothe rear transverse brace, 17, of the upper frame, 1, and thecorresponding parallel brace of the lower frame, 2. Between the saidbearings a pulley, 35, is keyed to the shaft, and to the upper portionextending above the bearings two cutterheads, 36, are secured one abovethe other, adapted to receive the cutter bars or blades 37. Thcsaidcutter-blades finish the edge of the shingles after having passedthrough the independent roughing cutter heads and knives 30 and 31, andare therefore of more or less similar shape to the aforesaidroughing-heads. The form of cutter heads and blades may be varied toproduce any configuration of edge required by the operator with littletrouble and in a short space of time.

The various pulleys mentioned in connection with the machine are adaptedto be rotated by the. independent lines of belting 41, 42, 43, 44, and45, which run ever larger pulleys, 46 47 48 49, and the extreme frontsmall pulley, 50, which is in line with pulley 19 of the vertical shaft18, through which motion is conveyed to the rotary table. The saidpulleys are usually mounted upon a shaft, 51., extending longitudinallyparallel with one side of said machine, which shaft receives motionusually through a drive-pulley, 53, mounted on the end thereof.

The upper -roughing cutter-head is rotated by means of the belt 42,passing over pulleys 47 and 32, the lower roughing-cutter through belt41, passing over pulleys 46 and 29, and the finishing-cutters receivemotion through crossbelt 44, engaging pulleys 49 and 35, while the upperhorizontal cutter is revolved by the belt 43, running over pulleys 4Sand 12. All the cutters are turned at a high rate of speed, the tableonly revolving with a slow motion.

In the operation of my machine, a pattern, 52, representing the form inwhich the shingles arc to be out is detachably clamped or bolted to theface of one or more of the radial arms 6, the jointed longitudinal edgebearing upon the circular plates of the table and the fancy-cut edgethereof extending outward, slightly bearing against the semicircularguide 26. The pattern is now brought in registry with the cutter-headsand the cutter knives or bars thereon are adj ustcd to said pattern andsecured in position upon the heads for work. The shingles are now packedin the compartments? of the rotary table just as they leave theshinglc-sawthat is, with one longitudinal edge jointed and the endssquared, as shown in Fig. 4. hen the shingles have been packed in saidcompartments with their jointed edge bearing upon the table, as shown inFig. 1, the machine is put in motion and the table, revolving from leftto right with a slow motion, carries the shingles nearly in contact withthe guide 26, which serves to give them a uniform contour, and,leavingsaid guide, the said bunched shingles are brought in contact with theindependent cutters 30 and 31, which cutters roughly shape the ends toconform with the pattern. As the table revolves farther around, therotating horizontal cutter suspended above said table joints the upperends, left unjointed by the saw, and finally the shingles are carried bythe table between the cutters 36, where they are finished smoothly. Whena compartment containing finished shingles is brought in front of theoperator, who stands at the cutaway portion of the frame, (shown in Fig.1,) thesaid opcratorremovesthecompleted shin glcs therefrom andsubstitutes therefor oth* ers uncut. The finished shingle, as cut by thepattern shown in the drawings, is illustrated in Fig. 5. Upon a machineconstructed as above described any desired shape may be imparted to theend of a shingle.

Having thus described myinvention, whatI claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with a frame carrying cutters and having a rotarytable pivoted thereon, and provided with radial arms, of a semicircularguide-bar attached to said frame and partially surrounding said table,said guide-bar having one end disposed to permit of the close approachthereto of the arms, while its other end is distant from said arms,substantially as shown and described, and for the purpose herein setforth.
